Inclusion criteria |
Randomized controlled trials |
Outcome |
Pain or pain relief |
Results: Effectiveness |
9 randomized controlled trials including:
1 with failed back surgery syndrome (20;69;78)
1 with complex regional pain syndrome (72;79;80)
1 with painful diabetic neuropathy (58)
2 with critical limb ischemia (not applicable to MAS systematic review)
4 with angina trials (not applicable to MAS systematic review)
Failed back surgery syndrome:
Complex regional pain syndrome:Kemler et al. (72;79;80) as reported by Mailis-Gagnon et al., (51); Cameron, (49); Turner, (19); and Grabow, (59). Painful diabetic neuropathy:
Tesfaye et al. (58) reported results from a crossover design study in which 10 patients with neuropathic pain for less than 1 year were treated with active spinal cord stimulation for 2 days and then with placebo stimulation for 2 days.
Results indicated significant decrease in pain as measured by the visual analogue scale with active vs. placebo stimulation (P = .004)
Critical limb ischemia and angina pain:
|
Results: Safety |
Failed back surgery syndrome:Complex regional pain syndrome:
2 patients with a dural puncture (1 developed a headache)
1 patient with an infection at the implantation site of the pulse generator (IPG) requiring ex-plantation and subsequent reimplantation.
6 patients requiring either plug wound or IPG implantation site revision.
1 patient with a defective lead requiring replacement.
6 episodes of unsatisfactory lead positioning needing correction.
Painful diabetic neuropathy:
2 patients migrated leads requiring reinsertion
2 patients with superficial wound infections requiring antibiotic.
1 patient died due to unrelated causes
Critical limb ischemia: Adverse events with spinal cord stimulation:Adverse events with best medical treatment:

Conclusion reported in the ASERNIP-S Health Technology Assessment |
Spinal cord stimulation is effective in relieving pain in some of the studies.
Spinal cord stimulation appears to be relatively safe although long-term safety and effectiveness of SCS (beyond 2 years) has not been reported in the studies reviewed.
